Abstract: 220,922. Lilienfeld, J. E. Aug. 21, 1923, [Convention date]. Electric-lamp lanterns and casings ; lamps for concentrating light on definite spot near the lamp- An incandescent electric lamp comprises a spiral, preferably carbon, filament 1, arranged around one focus F<1> of an ellipsoidal reflector, so that a considerable portion of rays may concentrate substantiallv at the second focus, which is in front of the bulb. The filament 1 is arranged so that the larger part is between the two foci and it may be cylindrical or conical, the apex of the cone being arranged a little beyond the focus F<1> towards the vertix of the reflector. The rear portion 9 of the lamp casing 5 is made of gauze or perforative sheet metal and the front portion of metal or of frosted glass, with an opening 6 for the passage of the concentrated rays. A reflecting-cone 8 may be provided. The neck 12 of the casing 5 is secured by screws 15 in a tube 13, which is inserted in a handle 14 and the parts are fixed in adjusted position by soldering or by plaster, the lamp socket being screwed into a tube 16. The filament 1 is connected to electric leads by the tube 16, a contact 12 and a switch 19. Examples of the distance between the vertix and first focus and between the two foci of the reflector are given. The Specification, as open to inspection under Sect. 91 (3) (a) states also that the casing 5 may be made in three parts and provided with a focusing-lens. This subject-matter does not appear in the Specification as accepted.

Abstract: 1438456 Thread milling; gauging BURWELL REED & KINGHORN Ltd 24 March 1975 [5 Feb 1974] 05238/74 Headings B3K and B3B A thread milling machine comprises a cutter head 15 to which a rotary cutter is attached to be driven by a motor 19, the cutter head being mounted for vertical movement on a column 3 extending from a base 1; a rotary work table assembly 5 is mounted on the lower part of the column 3 vertically below the cutter head for rotation about a vertical axis by way of a belt drive 22 by a handle and spindle 20, 23. The cutter head 15 may be adjusted vertically relative to the work table 7 by a screw and wheel 25 and is also provided with a graduated dial 27 for setting the helix angle of the cutter by inclination of the cutter head. The work table assembly is tranversely displaceable on a slideway 35 by a hand wheel 49. In operation a workpiece is secured in an adaptor 11 of the table 7 and an appropriate cutter secured in a collet attachment 17 of the head 15, the angle of the cutter is adjusted by the dial 27 and the head lowered by the wheel 25 to the starting position for forming a thread on the workpiece. The desired depth of thread is obtained by adjusting the work-table along the slide 35 by wheel 49, the table then being locked in position horizontally and the thread is formed by driving the cutter and rotating the work table by way of the handle 23 and belt 22 whilst moving the table vertically by a screw and nut assembly located within the table assembly. The screw and nut assembly is selected prior to the thread milling operation so that the workpiece will have the desired thread pitch. When milling a thread of variable depth, the table 7 is not locked in the horizontal direction and the horizontal movement of the table, after the initial setting, is controlled by a cam 55 attached to the table 7 which co-operates a roller arm 41 to displace the table along the slide 37 and hence the workpiece to vary the depth of thread, the table being returned to its initial position, when the roller leaves the cam, by way of springs 57, 59. An indexing disc may be located on the work-table 7 and is marked with indicia representing stop and start positions for various thread configurations.

Title: Improvements in deseaming or desurfacing metal bodies
IPC: B23K7/06
Filed: 1940-03-27
Abstract: 539,470. Blowpipe burners. LINDE AIR PRODUCTS CO. March 27, 1940, No. 5489. Convention date, April 22, 1939. [Class 75 (i)] [Also in Group XXII] In de-seaming or de-surfacing metal bodies such as billets, blooms, slabs &c. a jet of oxidizing gas at de-seaming or de-surfacing velocity is impinged along and obliquely against the surface and at the same time a jet of oxidizing gas at low velocity is impinged against the surface at one or both sides thereof. The formation of fins at the edges is thus inhibited by oxidizing the molten metal in the slag so as to obtain a brittle slag without damaging the base metal of the work. The de-seaming blowpipe P may have a main nozzle N containing a central oxygen orifice O supplied with oxygen at deseaming velocity, e.g. 500-1,000 feet per sec., surrounded with pre-heating jets H. On the nozzle is mounted a yoke Y having a pair of auxiliary nozzles A supplied with oxygen at low velocity, e.g. from 50-150 feet per sec. The supply may be from a separate source or from the main source through a throttle valve. The yoke may be free to turn on the nozzle so that the nozzles A are automatically held in proper position by resting the yoke on the surface. The nozzles A are inclined downwardly and inwardly with respect to the jet O so as to counteract the tendency of the jet O to blow the hot material over the opposite edges of the surfaces. De-surfacing of a relatively wide surface may be effected by using an apparatus with a bank of nozzles used as N carried by a head with an auxiliary nozzle such as A at one or both sides of the head. Specifications 494,218 and 538,092 are referred to.

Abstract: 1420068 Discharging by fluidization G J LACEY 4 May 1973 [7 Feb 1972] 5538/72 Heading B8A Granular material is discharged from a storage container through openings controlled by dampers and communicating with channels which are provided with fluidizing air through openings in adjacent ducts leading from a plenum chamber, the entry of air into the ducts from the plenum chamber also being controlled by dampers. The material then passes on to a conveyer running parallel to the plenum chamber. In the Figure, granular material enters the storage container from a conveyer via outlet 27 and feed shoot 26. Air from a plenum chamber is allowed into ducts 3 when dampers 9 are raised by door pulls 10. The air flows out through openings 6 and down towards the floor and along the floor, carrying fluidized material towards outlets 8, controlled by dampers 18, and on to a conveyer which either discharges the material, e.g. into a vehicle or recirculates it to conveyer outlets 27 and back into the container for conditioning. The apparatus may also be used for drying grain.

Title: Process of preparing titanium oxide and pigments made therefrom
IPC: C22B34/12
Filed: 1931-02-21
Abstract: Ilmenite, sodium carbonate, and carbon are heated together, say to 800 DEG  C., in a rotary furnace, and the resulting mass discharged into cold water.  The disintegrated product is leached with weak basic lye, say at 80 DEG  C., to remove alkali and soluble silicate and aluminate, sodium carbonate being recovered for re-use from the solution by treatment with carbon dioxide recovered in the heating process.  Iron is largely removed from the residual mass by treatment with hot dilute sulphuric acid, and the titanium then brought into solution by concentrated sulphuric acid at initial temperatures of 150-180 DEG  C. with subsequent increase to 200-225 DEG  C.  From the solution obtained titanium oxide is obtained by hydrolysis, composite pigments resulting if barium carbonate is first added.

Title: Method of and apparatus for amplifying electric signal impulses
IPC: H03F3/02
Filed: 1925-03-03
Abstract: 232,183. Pupin, M. I., and Herbig, H. F. April 11, 1924, [Convention date]. Thermionic amplifiers and detectors.-Electrical impulses, particularly those used in cable telegraphy, are amplified by the combined action of a light-sensitive device and a thermionic amplifier, the arrangement being characterized by the use of a biasing or zeroizing shunt inserted across the final recording-device. Currents flowing in a circuit 11 cause a galvanometer 12 to vary the light incident upon a photo-electric cell 1. This creates potential differences across a resistance 2, which are applied across the grid 5 and filament of an amplifier 4 and give rise in turn to deflections in a recording galvanometer 9, across which is shunted a battery 13 and variable resistance 14. By a suitable initial setting of the illumination of the cell 1 from the galvanometer 12 for zero current, positive and negative pulses of signal current are separately recorded. The cell 1 comprises a barium cathode a, and a wire or plate grid or anode b, contained within an evacuated or argon or helium filled bulb.
